Oh, Tool. Such jokers! Including 3D glasses with the artwork for your new album, writing songs with titles like "Rosetta Stoned", ambushing your opening band while wearing ape costumes. It's just a constant party with you guys, right?

Said ambush took place last night at Zurich, Switzerland's Hallenstadium, while Tool tourmates Mastodon were busy melting Swiss faces. We're not sure what, exactly, happened, but judging from these photos, it appears that organ grinding was involved.

Think that's funny? How about this: Mastodon are nominated for a Grammy for Best Metal Performance for their song "Colony of Birchmen" from Blood Mountain. Now that's hilarious.
